Disparate Patient Advocacy When Facing Unaffordable and Problematic Medical Bills.

Importance: People in the US face high out-of-pocket medical expenses, yielding financial strain and debt. Objective: To understand how households respond to medical bills they disagree with or cannot afford. Design, Setting, and Participants: A retrospective cohort study was carried out using a survey fielded between August 14 and October 14, 2023. The study included a random sample of adult (aged ≥18 years) survey respondents from the Understanding America Study (UAS). Participant responses were weighted to be nationally representative. The analysis took place from November 3, 2023, through January 8, 2024. Main Outcomes and Measures: Respondents reported if their household received a medical bill that they could not afford or did not agree with in the prior 12 months, and if anyone contacted the billing office regarding their concerns. Those who did reach out were asked about their experience and those who did not were asked why. Results: The survey was sent to 1233 UAS panelists, of which 1135 completed the survey, a 92.1% cooperation rate. Overall, 1 in 5 of the 1135 respondents received a medical bill that they disagreed with or could not afford. Leading bill sources were physician offices (66 [34.6%]), emergency room or urgent care (22 [19.9%]), and hospitals (31 [15.3%]), and 136 respondents (61.5%) contacted the billing office to address their concern. A more extroverted and less agreeable personality increased likelihood of reaching out. Respondents without a college degree, lower financial literacy, and the uninsured were less likely to contact a billing office. Among those who did not reach out, 55 (86.1%) reported that they did not think it would make a difference. Of those who reached out, 37 (25.7%) achieved bill corrections, better understanding (16 [18.2%]), payment plans (18 [15.5%]), price drop (17 [15.2%]), financial assistance (10 [8.1%]), and/or bill cancellation (6 [7.3%]), while 32 (21.8%) said that the issue was unresolved and 23.8% reported no change. These outcomes aligned well with respondents' billing concerns with financial relief for 75.8% of respondents reaching out about an unaffordable bill, bill corrections for 73.7% of those who thought there was mistake, and a price drop for 61.8% of those who negotiated. Conclusions and Relevance: This cross-sectional survey of a representative sample of patients in the US found that most respondents who self-advocated achieved bill corrections and payment relief. Differences in self-advocacy may be exacerbating socioeconomic inequalities in medical debt burden, as those with less education, lower financial literacy, and the uninsured were less likely to self-advocate. Policies that streamline the administrative burden or shift it from patients to the billing clinician may counter these disparities.

FDA, CDC, and NIH Co-sponsored Public Workshop Summary-Development Considerations of Antimicrobial Drugs for the Treatment of Gonorrhea.

There is an unmet need for developing drugs for the treatment of gonorrhea, due to rapidly evolving resistance of Neisseria gonorrhoeae against antimicrobial drugs used for empiric therapy, an increase in globally reported multidrug resistant cases, and the limited available therapeutic options. Furthermore, few drugs are under development. Development of antimicrobials is hampered by challenges in clinical trial design, limitations of available diagnostics, changes in and varying standards of care, lack of robust animal models, and clinically relevant pharmacodynamic targets. On April 23, 2021, the U.S. Food and Drug Administration; Centers for Disease Control and Prevention; and National Institute of Allergy and Infectious Diseases, National Institutes of Health co-sponsored a workshop with stakeholders from academia, industry, and regulatory agencies to discuss the challenges and strategies, including potential collaborations and incentives, to facilitate the development of drugs for the treatment of gonorrhea. This article provides a summary of the workshop.

Acceptability of Hospital-at-Home Care and Capacity for Caregiver Burden.

This study surveys a representative US population about aspects of hospital-at-home care, including acceptability and willingness to perform caregiving tasks.

Deductible double jeopardy: patients may pay more out of pocket when pregnancy crosses 2 years.

OBJECTIVES: This study explores the concern that annual high-deductible commercial insurance plan design may yield higher out-of-pocket costs when an episode of maternity care spans 2 years, exposing patients to their cost-sharing limits twice during their episode of care. STUDY DESIGN: Cross-sectional study of Health Care Cost Institute commercial claims. METHODS: The study sample comprises 1,379,300 deliveries among high-deductible health plan enrollees in years 2012 through 2021. Patients' mean cost sharing is calculated across all service types for 3 time periods: (1) delivery hospitalization, (2) maternity episode from 40 weeks prior to delivery hospitalization through 12 weeks after discharge, and (3) extended period spanning 3 years from January of the year before delivery through December of the year after delivery. RESULTS: For each of the 3 episode measurements, mean out-of-pocket spending is highest among those who deliver in January and declines in each subsequent month until August and September (the delivery months with most pregnancy and postpartum periods within the same year), then flattens for the remainder of the year. Mean cost sharing for the maternity episode was $6308 in January and $4998 in December, a difference of $1310. Patients delivering in January also had mean out-of-pocket costs $1491 greater for delivery hospitalization and $1005 greater over the 3-year period than patients delivering in December. CONCLUSIONS: Higher out-of-pocket spending is observed when patients face their cost-sharing limits twice within an episode of maternity care, and this difference persists even when evaluating 3 calendar years of patients' out-of-pocket spending.

Small but mighty: the rise of microprotein biology in neuroscience.

The mammalian central nervous system coordinates a network of signaling pathways and cellular interactions, which enable a myriad of complex cognitive and physiological functions. While traditional efforts to understand the molecular basis of brain function have focused on well-characterized proteins, recent advances in high-throughput translatome profiling have revealed a staggering number of proteins translated from non-canonical open reading frames (ncORFs) such as 5' and 3' untranslated regions of annotated proteins, out-of-frame internal ORFs, and previously annotated non-coding RNAs. Of note, microproteins < 100 amino acids (AA) that are translated from such ncORFs have often been neglected due to computational and biochemical challenges. Thousands of putative microproteins have been identified in cell lines and tissues including the brain, with some serving critical biological functions. In this perspective, we highlight the recent discovery of microproteins in the brain and describe several hypotheses that have emerged concerning microprotein function in the developing and mature nervous system.

Financial assistance and payment plans for underinsured patients shopping for "shoppable" hospital services.

Recent price transparency laws are designed to better inform patients as they compare hospital options and "shop" for health care services. In addition to prices, underinsured patients seeking care need information on financial assistance, discounts, payment plans, and upfront payment requirements to compare the affordability of care across hospitals. Little is known about the availability of this information and the experience of prospective patients seeking it. We contacted a random sample of 10% of general short-term hospitals across the United States in this "secret shopper" telephone study to assess financial options and navigation challenges faced by underinsured patients in need of a non-emergency procedure. The administrative friction was substantial. Most hospitals have 3 siloed offices for (1) financial assistance, (2) payment plans and discounts, and (3) upfront payment requirements. All relevant offices were unreachable in 3 attempted calls at 18.1% of hospitals. Among hospitals with available information, the majority have financial options for patients: 86.7% of hospitals offer financial assistance and 97.0% of hospitals offer payment plans to underinsured patients for non-emergency care. The length and terms of payments plans varied widely for hospital-administered and third-party financing arrangements. Upfront payments were sometimes required, potentially posing barriers for patients without cash or credit access.

Beyond active learning: Using 3-Dimensional learning to create scientifically authentic, student-centered classrooms.

In recent years, much of the emphasis for transformation of introductory STEM courses has focused on "active learning", and while this approach has been shown to produce more equitable outcomes for students, the construct of "active learning" is somewhat ill-defined and is often used as a "catch-all" that can encompass a wide range of pedagogical techniques. Here we present an alternative approach for how to think about the transformation of STEM courses that focuses instead on what students should know and what they can do with that knowledge. This approach, known as three-dimensional learning (3DL), emerged from the National Academy's "A Framework for K-12 Science Education", which describes a vision for science education that centers the role of constructing productive causal accounts for phenomena. Over the past 10 years, we have collected data from introductory biology, chemistry, and physics courses to assess the impact of such a transformation on higher education courses. Here we report on an analysis of video data of class sessions that allows us to characterize these sessions as active, 3D, neither, or both 3D and active. We find that 3D classes are likely to also involve student engagement (i.e. be active), but the reverse is not necessarily true. That is, focusing on transformations involving 3DL also tends to increase student engagement, whereas focusing solely on student engagement might result in courses where students are engaged in activities that do not involve meaningful engagement with core ideas of the discipline.

Vaccine value profile for Klebsiella pneumoniae.

Klebsiella pneumoniae causes community- and healthcare-associated infections in children and adults. Globally in 2019, an estimated 1.27 million (95% Uncertainty Interval [UI]: 0.91-1.71) and 4.95 million (95% UI: 3.62-6.57) deaths were attributed to and associated with bacterial antimicrobial resistance (AMR), respectively. K. pneumoniae was the second leading pathogen in deaths attributed to AMR resistant bacteria. Furthermore, the rise of antimicrobial resistance in both community- and hospital-acquired infections is a concern for neonates and infants who are at high risk for invasive bacterial disease. There is a limited antibiotic pipeline for new antibiotics to treat multidrug resistant infections, and vaccines targeted against K. pneumoniae are considered to be of priority by the World Health Organization. Vaccination of pregnant women against K. pneumoniae could reduce the risk of invasive K.pneumoniae disease in their young offspring. In addition, vulnerable children, adolescents and adult populations at risk of K. pneumoniae disease with underlying diseases such as immunosuppression from underlying hematologic malignancy, chemotherapy, patients undergoing abdominal and/or urinary surgical procedures, or prolonged intensive care management are also potential target groups for a K. pneumoniae vaccine. A 'Vaccine Value Profile' (VVP) for K.pneumoniae, which contemplates vaccination of pregnant women to protect their babies from birth through to at least three months of age and other high-risk populations, provides a high-level, holistic assessment of the available information to inform the potential public health, economic and societal value of a pipeline of K. pneumoniae vaccines and other preventatives and therapeutics. This VVP was developed by a working group of subject matter experts from academia, non-profit organizations, public-private partnerships, and multi-lateral organizations, and in collaboration with stakeholders from the WHO. All contributors have extensive expertise on various elements of the K.pneumoniae VVP and collectively aimed to identify current research and knowledge gaps. The VVP was developed using only existing and publicly available information.

This cross-sectional study reports the allowed reimbursement amounts for inpatient COVID-19 care for different types of hospitals.

Repeated seizures lead to progressive ventilatory dysfunction in SSKcnj16-/- rats.

Patients with uncontrolled epilepsy experience repeated seizures putting them at increased risk for sudden unexpected death in epilepsy (SUDEP). Data from human patients have led to the hypothesis that SUDEP results from severe cardiorespiratory suppression after a seizure, which may involve pathological deficiencies in the brainstem serotonin (5-HT) system. Rats with a genomic Kcnj16 mutation (SSKcnj16-/- rats) are susceptible to sound-induced generalized tonic-clonic seizures (GTCS) which, when repeated once daily for up to 10 days (10-day seizure protocol), increased mortality, particularly in male rats. Here, we test the hypothesis that repeated seizures across the 10-day protocol will cause a progressive ventilatory dysfunction due to time-dependent 5-HT deficiency. Initial severe seizures led to ictal and postictal apneas and transient decreases in breathing frequency, ventilatory drive, breath-to-breath variability, and brief hypoventilation. These seizure-induced effects on ventilation were exacerbated with increasing seizures and ventilatory chemoreflexes became further impaired after repeated seizures. Tissue analyses of key brainstem regions controlling breathing showed time-dependent 5-HT system suppression and increased immunoreactivity for IBA-1 (microglial marker) without changes in overall cell counts at 3, 7, and 10 days of seizures. Fluoxetine treatment in SSKcnj16-/- rats prevented repeated seizure-induced progressive respiratory suppression but failed to prevent seizure-related mortality. We conclude that repeated seizures cause a progressive compromise of ventilatory control in the immediate postictal period largely mediated by serotonin system suppression in brainstem regions of respiratory control. However, other unknown factors contribute to overall survival following repeated seizures in this model.NEW & NOTEWORTHY This study demonstrated that repeated seizures in a novel rat model (SSKcnj16-/- rats) caused a progressively greater ventilatory dysfunction in the immediate postictal period associated with brainstem serotonin (5-HT) suppression. Augmenting brain 5-HT with a selective serotonin reuptake inhibitor prevented the progressive ventilatory dysfunction induced by repeated seizures but failed to prevent seizure-related mortality, suggesting that repeated seizures may lead to cardiorespiratory suppression and failure through multiple mechanisms.

A NPAS4-NuA4 complex couples synaptic activity to DNA repair.

Neuronal activity is crucial for adaptive circuit remodelling but poses an inherent risk to the stability of the genome across the long lifespan of postmitotic neurons1-5. Whether neurons have acquired specialized genome protection mechanisms that enable them to withstand decades of potentially damaging stimuli during periods of heightened activity is unknown. Here we identify an activity-dependent DNA repair mechanism in which a new form of the NuA4-TIP60 chromatin modifier assembles in activated neurons around the inducible, neuronal-specific transcription factor NPAS4. We purify this complex from the brain and demonstrate its functions in eliciting activity-dependent changes to neuronal transcriptomes and circuitry. By characterizing the landscape of activity-induced DNA double-strand breaks in the brain, we show that NPAS4-NuA4 binds to recurrently damaged regulatory elements and recruits additional DNA repair machinery to stimulate their repair. Gene regulatory elements bound by NPAS4-NuA4 are partially protected against age-dependent accumulation of somatic mutations. Impaired NPAS4-NuA4 signalling leads to a cascade of cellular defects, including dysregulated activity-dependent transcriptional responses, loss of control over neuronal inhibition and genome instability, which all culminate to reduce organismal lifespan. In addition, mutations in several components of the NuA4 complex are reported to lead to neurodevelopmental and autism spectrum disorders. Together, these findings identify a neuronal-specific complex that couples neuronal activity directly to genome preservation, the disruption of which may contribute to developmental disorders, neurodegeneration and ageing.

Ground Ambulance Billing And Prices Differ By Ownership Structure.

The No Surprises Act prohibits most surprise billing but notably does not apply to ground ambulance services. In this study we created a novel data set that identifies the ownership structure of ground ambulance organizations to compare pricing and billing between private- and public-sector ambulances, with a specific focus on organizations owned by private equity or publicly traded companies. Overall, we found that 28 percent of commercially insured emergency ground ambulance transports during the period 2014-17 resulted in a potential surprise bill. Our analysis illustrates that being transported by a private-sector ambulance in an emergency comes with substantially higher allowed amounts, patient cost sharing, and potential surprise bills compared with being transported by a public-sector ambulance. Further, allowed amounts and cost sharing tended to be higher for private equity- or publicly traded company-owned ambulances than other private-sector ambulances. These findings highlight substantial patient liability and important differences in pricing and billing patterns between public- and private-sector ground ambulance organizations.

Comparison of Estimated No Surprises Act Qualifying Payment Amounts and Payments to In-Network and Out-of-Network Emergency Medicine Professionals.

Importance: The No Surprises Act (NSA), which took effect on January 1, 2022, applies a qualifying payment amount (QPA) as an out-of-network payment reference point. An understanding of how QPA measures compare with the in-network and out-of-network payments physicians received before the NSA implementation may be useful to policy makers and stakeholders. Objective: To estimate the QPA for geographic and funding markets and compare QPA estimates with in-network and out-of-network payments for 2019 emergency medicine claims. Design, Setting, and Participants: This cross-sectional study of US commercial insurance claims assessed the Health Care Cost Institute's 2019 commercial professional emergency medicine claims (Current Procedural Terminology [CPT] codes 99281-99285 and 99291) and included enrollees in commercial health maintenance organizations, exclusive provider organizations, point of service, and preferred provider organizations self-funded and fully insured through Aetna, Humana, and some Blue Health Intelligence plans. Claims with missing or inconsistent data fields were excluded. Data were analyzed November 1, 2021, to April 7, 2022. Main Outcomes and Measures: The QPA was calculated as the median allowed amount of all observed claims within strata defined by geographic region, CPT code, and funding market. For each stratum, the ratio of mean in-network allowed amounts to QPAs and mean out-of-network allowed amounts to QPAs were calculated. Then the volume-weighted mean of these ratios was computed across CPT codes within each geographic and funding market stratum. Results: The analytic sample included 7 556 541 professional emergency claims with a mean (SD) allowed amount of $313 ($306) and mean (SD) QPA of $252 ($133). Among the 650 geographic and market strata in the sample, the mean in-network allowed amounts were 14% (ratio, 0.96) higher than the estimated QPA. For the subset of strata with a sufficient sample of out-of-network claims (n = 227), the mean out-of-network payments were 112% (ratio, 2.12) higher than the QPA. More generous out-of-network payments were from self-funded plans (120% [ratio, 2.20] higher than the QPA estimate) vs fully insured plans (43% [ratio, 1.43] higher than the QPA estimate). Mean in-network allowed amounts for nonphysician clinicians were 4% (ratio, 1.04) lower than the QPA, whereas mean in-network allowed amounts for physicians were 15% (ratio, 1.15) higher than the QPA estimates. These differences remained after adjusting for geographic region. Conclusions and Relevance: The findings of this cross-sectional study of US commercial insurance claims suggest that the NSA may have heterogeneous implications for out-of-network payments and negotiating leverage experienced by emergency medicine physicians in different geographic markets, with the potential for greater implications in the self-funded market.

Developmental dynamics of RNA translation in the human brain.

The precise regulation of gene expression is fundamental to neurodevelopment, plasticity and cognitive function. Although several studies have profiled transcription in the developing human brain, there is a gap in understanding of accompanying translational regulation. In this study, we performed ribosome profiling on 73 human prenatal and adult cortex samples. We characterized the translational regulation of annotated open reading frames (ORFs) and identified thousands of previously unknown translation events, including small ORFs that give rise to human-specific and/or brain-specific microproteins, many of which we independently verified using proteomics. Ribosome profiling in stem-cell-derived human neuronal cultures corroborated these findings and revealed that several neuronal activity-induced non-coding RNAs encode previously undescribed microproteins. Physicochemical analysis of brain microproteins identified a class of proteins that contain arginine-glycine-glycine (RGG) repeats and, thus, may be regulators of RNA metabolism. This resource expands the known translational landscape of the human brain and illuminates previously unknown brain-specific protein products.

Insurers negotiate lower hospital prices for HIX than for commercial groups.

OBJECTIVES: This study investigates a sample of the pricing data released by hospitals under the price transparency law effective January 2021 to better understand the prices paid by health insurance exchange (HIX) plans relative to commercial group and Medicare Advantage plans. STUDY DESIGN: Cross-sectional analysis of hospital pricing data. METHODS: We compared allowed amounts for 25 common inpatient services and 56 common outpatient services across 22 hospital-insurer dyads, selected by the availability of plan-specific pricing data from the top 100 hospitals by bed counts and the top 100 hospitals by gross revenue based on 2017 CMS data. RESULTS: Insurers in our sample generally negotiated allowed amounts for their HIX plans that were lower than their commercial group rates and well above their Medicare Advantage contracts within the same hospital. CONCLUSIONS: Allowed amounts for HIX plans were generally lower than commercial group rates and higher than Medicare Advantage rates. Better information on HIX pricing is needed as the federal government and states consider additional ways to expand health care coverage, such as public options or expanded Medicaid or Medicare eligibility.

Medicare Advantage Plans Pay Large Markups To Consolidated Dialysis Organizations.

The 21st Century Cures Act of 2016 lifted regulations prohibiting Medicare Advantage (MA) enrollment after patients initiate dialysis, starting in 2021, and early reports indicate increased MA enrollment among such patients. Large shifts into Medicare Advantage could disrupt the market because the consolidated dialysis industry can negotiate payment from MA plans that is higher than that for fee-for-service Medicare. For three large insurers representing 48 percent of the 2016-17 MA market, we found that MA plans paid 27 percent more than fee-for-service Medicare. Larger dialysis center chains commanded higher markups. Virtually all facilities of the two largest chains were in network, suggesting that they leverage their market power into all-or-nothing negotiations with plans. Policy makers should consider regulations that limit market consolidation among dialysis providers, as well as their ability to exercise that power in the MA market.

Physician Compensation Arrangements and Financial Performance Incentives in US Health Systems.

Importance: Public and private payers continue to expand use of alternative payment models, aiming to use value-based payment to affect the care delivery of their contracted health system partners. In parallel, health systems and their employment of physicians continue to grow. However, the degree to which health system physician compensation reflects an orientation toward value, rather than volume, is unknown. Objective: To characterize primary care physician (PCP) and specialist compensation arrangements among US health system-affiliated physician organizations (POs) and measure the portion of total physician compensation based on quality and cost performance. Design Setting and Participants: This study was a cross-sectional mixed-methods analysis of in-depth multimodal data (compensation document review, interviews with 40 PO leaders, and surveys conducted between November 2017 and July 2019) from 31 POs affiliated with 22 purposefully selected health systems in 4 states. Data were analyzed from June 2019 to September 2020. Main Outcomes and Measures: The frequency of PCP and specialist compensation types and the percentage of compensation when included, including base compensation incentives, quality and cost performance incentives, and other financial incentives. The top 3 actions physicians could take to increase their compensation. The association between POs' percentage of revenue from fee-for-service and their physicians' volume-based compensation percentage. Results: Volume-based compensation was the most common base compensation incentive component for PCPs (26 POs [83.9%]; mean, 68.2% of compensation; median, 81.4%; range, 5.0%-100.0% when included) and specialists (29 POs [93.3%]; mean, 73.7% of compensation; median, 90.5%; range, 2.5%-100.0% when included). While quality and cost performance incentives were common (included by 83.9%-56.7% of POs for PCPs and specialists, respectively), the percentage of compensation based on quality and cost performance was modest (mean, 9.0% [median, 8.3%; range, 1.0%-25.0%] for PCPs and 5.3% [median, 4.5%; range, 0.5%-16.0%] for specialists when included). Increasing the volume of services was the most commonly cited action for physicians to increase compensation, reported as the top action by 22 POs (70.0%) for PCPs and specialists. We observed a very weak, nonsignificant association between the percentage of revenue of POs from fee for service and the PCP and specialist volume-based compensation percentage (r = 0.08; P = .78 and r = -0.04; P = .89, respectively). Conclusions and Relevance: The results of this cross-sectional study suggest that PCPs and specialists despite receiving value-based reimbursement incentives from payers, the compensation of health system PCPs and specialists was dominated by volume-based incentives designed to maximize health systems revenue.

Patch-to-Seq and Transcriptomic Analyses Yield Molecular Markers of Functionally Distinct Brainstem Serotonin Neurons.

Acute regulation of CO2 and pH homeostasis requires sensory feedback from peripheral (carotid body) and central (central) CO2/pH sensitive cells - so called respiratory chemoreceptors. Subsets of brainstem serotonin (5-HT) neurons in the medullary raphe are CO2 sensitive or insensitive based on differences in embryonic origin, suggesting these functionally distinct subpopulations may have unique transcriptional profiles. Here, we used Patch-to-Seq to determine if the CO2 responses in brainstem 5-HT neurons could be correlated to unique transcriptional profiles and/or unique molecular markers and pathways. First, firing rate changes with hypercapnic acidosis were measured in fluorescently labeled 5-HT neurons in acute brainstem slices from transgenic, Dahl SS (SSMcwi) rats expressing T2/ePet-eGFP transgene in Pet-1 expressing (serotonin) neurons (SS ePet1-eGFP rats). Subsequently, the transcriptomic and pathway profiles of CO2 sensitive and insensitive 5-HT neurons were determined and compared by single cell RNA (scRNAseq) and bioinformatic analyses. Low baseline firing rates were a distinguishing feature of CO2 sensitive 5-HT neurons. scRNAseq of these recorded neurons revealed 166 differentially expressed genes among CO2 sensitive and insensitive 5-HT neurons. Pathway analyses yielded novel predicted upstream regulators, including the transcription factor Egr2 and Leptin. Additional bioinformatic analyses identified 6 candidate gene markers of CO2 sensitive 5-HT neurons, and 2 selected candidate genes (CD46 and Iba57) were both expressed in 5-HT neurons determined via in situ mRNA hybridization. Together, these data provide novel insights into the transcriptional control of cellular chemoreception and provide unbiased candidate gene markers of CO2 sensitive 5-HT neurons. Methodologically, these data highlight the utility of the patch-to-seq technique in enabling the linkage of gene expression to specific functions, like CO2 chemoreception, in a single cell to identify potential mechanisms underlying functional differences in otherwise similar cell types.
